THOMAS ANNIS, OF BATTLE CREEK, MICHIGAN, ASSIGNOR OF ONE-HALF TO CHARLESWVILLARD AND WVESLEY O. WILLIAMS, BOTH OF SAME PLACE.

ATTACHMENT FOR WINDMILLS.

SPECIFICATION forming part of Letters Patent No. 432,110, dated July 15,1890. 7

Application filed April 8, 1890. Serial No. 347,090. (No model.)

To all whom it may concern.-

Be it known that I, THOMAS ANNIS, a citizen of the United States,residing at Battle Creek, in the county of Calhoun and State ofMichigan, have invented certain new and useful Improvements inAttachments for lrVindmills, of which the following is a specification,reference being had therein to the accompanying drawings, forming a partthereof,

To an d wherein like letters of reference design ate similar parts inall the views.

The object of this improvement is to provide simple and effective meansfor altering and regulating the stroke of the power-transinitting rod ofthe engine, and it is particularly adapted to be applied to windmillsfor the adjustment of the length ofstroke of the pump-piston, wherebythe loss of powerof the mill and consequent volume of water elevatedfrom the well when the wind is light or fitful, caused by slight leaksin the pumpvalves constantly occurring, is overcome or in a measureneutralized, and the maximum of engine-power is utilized. I accomplishthis 2 5 desideratum by means of the novel mechanism now to bedescribed, as follows:

Referring to the drawings, Figure l represents a plan view of myinvention. Fig. 2 shows a vertical elevation of the same, and

Fig. 3 is ahorizontal or plan view of the powertransmitting andregulating beam.

A designates a vibratory rod or beam, made of wood or iron and formednearer one of its ends than its other with an angular bend,

3 5 which forms a journal I), on which said rod or beam vibratesvertically. This journal I) has its bearing in a box O, which is fixedto a transverse horizontal timber B or other suitable support. Near eachextremity of this rod or beam A, and projecting horizontally therefrom,is a series of wrist-pins a a a, of which any one of those at one end ofthe rod is pivotally engaged by an end of an engine orpower-transmitting rod w, while any one 5 of those at the opposite endof the rod is pivotally engaged by a link L, which connects said rod orbeam A with a rod or beam A, which is of the same construction as saidrod A, but is oppositely placed 011 the under side of the timber B. Thewrist-pins at the free end of this rod or beam A are pivotally engagedby an end of the pump-piston or power receiving rod.

On reference to Fig. 2 it will be seen that the bend in the rod orbeam Ais nearer that end ofthe same which is engaged by the powertransmittingrod 10, while the bend in the rod or beam A is nearer that end of thesame which is connected with ,the rod or beam A. By this constructionand the employment of 6: two rods or beams instead of one double theadjustment of stroke is obtained without in any way disturbing theposition of the windmill and pump-rods now in use.

The stroke of the power-receiving rod P is determined by the relativeposition of said rod, the power-transmitting rod, and the link Lthatisto say, to obtain the longest stroke of power-receiving rods the partsreferred to are located in the relative positions shown in the drawings,and to obtain the shortest stroke said parts will be in engagement withthose wrist-pins located nearest the journals of said rods or beams.

It is well known that with a light or fitful wind and slight leak ofpump-valve, to which all water-elevators are constantly subject, thefixed stroke of pump practically renders water elevating from deep wellsineffective. By the above simple construction the stroke of thepower-receiving rod can be adjusted to suit the condition of wind andleakage of valves, the slightest motion of the engine being utilized andthe engine-power placed under perfect control at all times.

Having now described my invention, what I believe to be new, and desireto secure by Letters Patent, is-

1. The combinatiomwith two vibratory rods or beams A A, each having aplurality of 0 wrist-pins at each end, the journals of said beams beinglocated different distances from the ends thereof, of a link connectingtogether the longer end of one rod or beam and the shorter end of theother, a power-transmitting 5 rod connected with the shorter end of rodor beam A, and a power-receiving rod connected with the longer end of,rod or beam A, substantially as shown and described.

2. Thecombination,withtwovibratoryrods 10:) or beams A A, each having anangularbend nearer one of its ends than its other end and bearing-boxesin which said bent portions are journaled, of a link connecting togetherthe longer end of one of said rods or beams and the shorter end of theother, a power-transmitting rod secured to the shorter end of rod orbeam A, and a poWer-receivin g rod secured to the longer end of rod orbeam A.

3. The combination, with the rods or beams A A, each having an angularbend nearer one of its ends than its other end and bearing-boxes inwhich said bent portions are journaled, of an adjustable link connectingtogether the longer end of rod or beam A and the shorter end of rod orbeam A, a

power-transmitting rod adjustably attached I 5 hereunto set my hand andsignature in the 20 presence of two witnesses.
